[IEEE 2018 IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM) - Nagoya (2018.8.29-2018.8.31)] 2018 IEEE International Workshop on Electromagnetics:Applications and Student Innovation Competition (iWEM) - Dual-Strip Monopole Antenna for USB Dongle Applications
摘要： In the paper, a design of dual-path folded monopole antenna for WLAN bands and 5G C-Band on dongle devices is presented. The antenna occupies an overall size of 30 × 10 × 4.8 mm3; the size of ground plane is 25 × 10 mm2. A Dual-strip monopole antenna with two bending plates to from a 3D structure excites the WLAN band and 5G C-band for USB dongle devices. The measured and simulated S11 of the antenna can be applied to WLAN bands (2.4 — 2.484, 5.15 — 5.35, and 5.725 — 5.825 GHz), 5G C-band (3.4 — 3.6 GHz). The more results of the antenna will be proposed and discussed in the paper.

[IEEE 2018 International Conference on Smart City and Emerging Technology (ICSCET) - Mumbai, India (2018.1.5-2018.1.5)] 2018 International Conference on Smart City and Emerging Technology (ICSCET) - IoT Based Facial Recognition Security System
摘要： In recent years, with the demand for better security, computers have played a large role. Due to their precision, large memory banks and high computing power, considerable development has been made in the area of face recognition. Computers now surpass humans in many face recognition tasks. A human being can remember limited number of faces. But a computer doesn’t have any limits, and can hence be used where large databases of facial records are needed. Such a facial recognition system has many potential applications including crowd and airport surveillance, private security and improved human-computer interaction. Such a system is perfectly suited to fix security issues and offer flexibility to smart house control. This project is aimed to be a complete system for face recognition: easy to build, cheap cost and effective. Main purpose is to be set as an alert for home visitors and provide information about the visitors in a dynamic website and phone application. It can also be used in other fields like industries, offices and even air-ports for identifying wanted people. Among the other bio-metric techniques, face recognition method offers one great advantage which is user friendliness.
